"[This Index is automatically generated from Jmake.rules file. Do not
edit this file or your changes will be lost. Edit Jmake.rules instead.]

This file contains a listing of all the macros that can be used in a
Jmakefile. Only a few of these should be used in the Jmakefile (they
are the top-level macros). However, some low-level ones may be useful,
but it is up to you to make that decision. This explains why this file
holds all the available macros for jmake.

In the following listing, the macros are separated by a line of dashes.
The signature of the macro is given, then a small comment of what it
does precedes the actual definition.

Lines preceded by '->' show the set of symbols defined when the macro is
used. Initialization lines are shown as-is, i.e. have the form SYM = val
while concatenation is shown by SYM += val (which means val is added to
the value of SYM).

Conditional lines are preceded by tests like (if SYM). This means the line
is to be kept if and only if the symbol SYM is defined. Other internal
requests are not formatted yet.
